What is a healthy first-pass resolution rate?
A healthy first-pass resolution rate (FPRR) is 90 percent or higher, meaning at least 90 percent of claims are paid in full on first submission without rework or appeal. Industry median is 80 to 85 percent.

Definition
First-pass resolution rate is the percentage of claims paid in full on first submission without requiring any additional action from the practice.
The detail
FPRR is a stricter metric than clean claim rate. Clean claim rate measures whether the claim was accepted by the clearinghouse and payer for processing. FPRR measures whether the claim was actually paid in full on first adjudication. The gap between the two is the work your billing team has to do on accepted-but-underpaid claims. HFMA lists first-pass resolution among its standard metrics but publishes no threshold for it, so treat the 90 percent figure commonly quoted as a working target rather than a standard. The biggest drivers of FPRR drag are bundling and unbundling errors, modifier issues, medical necessity documentation gaps, prior authorization mismatches, and contractual underpayments where the payer pays less than the contracted rate. The last category is often invisible because the claim shows as paid; only systematic contract reconciliation surfaces underpayments.

What this means for clinic owners
From Sorso
FPRR is the metric that catches contractual underpayments. If you only track clean claim rate and net collection rate, you can have an FPRR of 75 percent and never see it. Add it to your monthly KPI report and review it by payer.

What is a good clean claim rate?
The widely cited target is a 98 percent clean claim rate on first submission — HFMA repeats it in its 7 KPIs guidance, attributing the figure to Becker's ASC Review. Most outpatient practices run below that, and every point of the gap is revenue sitting in rework rather than in the bank.
What is a healthy denial rate?
A healthy initial denial rate is under 5 percent of submitted claims, and denial write-offs are worth tracking as a share of net patient revenue, the metric HFMA lists as AR-6. Industry averages have climbed above 11 percent.
What is modifier 25 used for?
Modifier 25 indicates that a significant, separately identifiable Evaluation and Management (E/M) service was performed by the same physician on the same day as a procedure, allowing both to be billed when properly documented.
What are the most common billing errors in healthcare?
The most common healthcare billing errors are eligibility verification failures, missing prior authorization, incorrect or missing modifiers (especially modifier 25 and 59), upcoding/downcoding, missing documentation for medical necessity, and timely filing failures.
How do I build a 13-week cash flow forecast for my medical practice?
A 13-week cash flow forecast is a weekly rolling projection of expected cash receipts and cash disbursements over the next 13 weeks (one quarter), updated weekly with actuals. For medical practices, it is the single most useful financial tool for managing the 30-90 day gap between service and collection. Build it from your billing system's expected reimbursement schedule and your fixed disbursement calendar (payroll, rent, taxes, debt service).
